探讨了烟草漂浮育苗期间育苗大棚的温度变化特征及不同节能增温材料对烟草幼苗生长的影响，结果表明，棚内平均温度比棚外温度高8.7℃；育苗池铺设节能增温材料后提高育苗池营养液温度0.55~2.85℃，出苗率、成苗率、壮苗率分别比对照增加5.6、3.2、3.9个百分点，成苗期提前6d；采用挤塑聚苯乙烯泡沫材料作为节能增温材料成本低，增温效果好，能较好解决烟草漂浮育苗前期营养液温度偏低的问题。

The charateristic of temperature varing in greenhouse during the tabacoo floating breed period and the impact of different energy-friendly warming material on tabacoo seedling were discussed.According to the results,the average temperature inside greenhouse was 8.7 celsius degree higher than that outside.After equipped with energy-friendly warming material in nursery pond,the temperature of nutrient solution in pond increased by 0.55 to 2.85 celsius degree,seedling emergerce rate,seedling establishment rate and strong seedling rate rose 5.6,3.2 and 3.9 percent respectively compared to controlled group,seedling establishment period saved 6 days.Extruded polystyrene,as a energy-efficient warming material,was cost-friendly and effective in increasing temperature,and extruded polystyrene could solve problems of low temperature of nutrient solution efficiently in primary stage of tabacoo floating breed period.
